Welcome!!!
I can understand how you want to give that "party boy" one last hoorah before stopping, but what if that were to be your final hoorah ever, would that be worth it? Probably not, because on the other side of the fence, the sober life you can experience a new life, a happier life, less financial strain, less mess on you, less embarrassment, shame, and so on...
I know we shouldn't play the "what-if" game, but I think this is a good reason to, you never know what on the other end of that party. Sounds like you have done enough of that?!
When I stopped using, I had to fully accept the fact I can not drink, alcohol and I have a very toxic relationship and I value my life more than any substance.
I hope you find your way, I will send some good energy to you!
Come here often, please.
Best wishes,
